DEPOST AND COLLECTION RECEPTACLE.

Application filed anuary 11, 1913.

To all whom 'it may concern Be it known that I, ERNEST E. SCHNELLE, ofRochester, in the county of Monroe and State of New York, have inventeda new and useful Improvement in Deposit and Collection Receptacles,which improvement is fully set forth in the following specification andshown in the accompanying drawings.

The present invention relates to deposit and collection receptacles andmore particularly to locking mechanism therefor of the type which isadapted to be set in order to permit the delivery door to be opened onceand, after being again closed, locked against further opening, and anobject of this invention is to provide a locking mechanism which may bereadily attached to deposit and collection recept-acles now in use,having but a few parts which are suitably inclosed against maliciousmanipulation, and being adjustable to receptacles of different sizes.

Another object of the invention is to provide a construction which ispositive in its act-ion and which is not liable to be renderedinoperative by a jarring action after once being set.

To these and other ends the invention consists in certain parts andcombinations of parts all of which will be hereinafter described, thenovel features being pointed out in the appended claims.

ln t-he drawings: Figure 1 is a section through a receptacle with thelocking mechanism shown in side elevation therein; Fig. 2 is ahorizontal section through the receptacle showing the locking mechanismin plan; Fig. 3 is a section on the line awa, Fig. 2, showing thelocking mechanism in locked position; Fig. 4iis a section showing thelocking mechanism set with the controlling door open; and Fig. 5 shows aview similar to Fig. 1 with the controlling door closed.

Referring more particularly to the drawing, 1 indicates the casing of adeposit and collection receptacle and 2 the door through which thedeposit is to be made. S indicates the keeper which, in this instance,is arranged upon the door 2, but it is to be understood that theinvention is not limited to this arrangement. This keeper may be locatedwithin a rectangular or open-ended boxlike casing 4 which hasoutwardly-turned flanges 5 on its opposite side walls throughSpecification of Letters Patent.

which the keeper is secured to the door 2. The keeper may be formed inone piece with the casing 4 and comprises an inwardly and upwardlyextending lip, its end serving as a shoulder for engagement by the latchto be described and its front face 5a forming an inclined surface onwhich the latch is adapted to ride to elfect the engagement between saidlatch and the keeper. The latch 6 is, in this instance, movablysupported bv the casing 1, but, it is to be understood, that theinvention is not limited to this arrangement, it being only necessarythat the latch @and the keeper 3 be mounted upon two dili'erent parts,one upon the door or other movable member and the other upon a casing orsuitable support. The latch, in this instance, is pivotally mounted at 7within an lnclosing casing 8, open at opposite ends and havingoutwardly-turned tianges 9 along its upper' side walls permitting theattachment of the casing 8 to the top of the casing 1 by means of screwsor other fastening devices.

The cross sectional area of the casing 8 is substantially the same asthe cross sectional area of the casing 4 so that each forms asubstantial continuation of the other when in abutment. The casing 8,when the casing 4 projects from the door 2, is secured to the casing 1 adistance away from the door opening equal to the lengt-h of the casingt. Vith this arrangement, the latch 6 projects from one end of thecasing 8 in order that it may coperate with the keeper 3 within thecasing t.

To the end of maintaining the latch out of cooperation with the keeperuntil the door 2 shall have been opened, there is provided a detainer 10arranged on the part, in this instance the door 2, which carries thekeeper 3 and adapted to hold the latch out of cooperation with thekeeper until the door is opened. In this instance, the nose of the latchdoes not engage directly with the detainer as there is provided acontrolling member 11 pivoted on a pin 7 to which the latch is pivoted,the latch and the member 11 respectively having cooperating portions 12and 13 which permit the latch to move away from the keeper independentlyof the controlling member 11 but which restrain the movement of thelatch toward the keeper except when the controlling member moves in thesame direction. 1t is apparent that this invention is not limited tomaking the controlling member 11 independent of the latch 6 asdescribed. The free end of this controlling lever cooperates with thedetaining member 10 and to the end that this controlling member may beset into cooperation wit-h the detainer 10 while the door 2 is closed,one of said parts is adapted to yield or move backwardly when the otheris moved in the same direction. In this instance, the detainer 10 hassuch yielding movement and, to this end, it is pivoted at 14 within thehousing 4, a spring 15 serving to hold a stop 16 thereon against thebottom of the housing t so that the detainer normally lies in detainingposition, that is, after it has been moved away from such position bythe movement of the latch, will move again to detaining positionimmediately prior to t-he setting of the latch.

The shifting of the latch away from the keeper while the door 2 isclosed and the resetting thereof may be accomplished in any suitablemanner. In this instance, the controlling member is the door 17a whichusually opens into the interior of the dwelling in which the receptacleis embodied. Preferably, connection between this door and the latch isestablished through the medium of a plunger which may be made of twoparts connected together in such a manner as to make the plungereXtensible. One of these parts, indicated at 17 is in the form of aslide movable in the bottom of the casing 8 and below the latch 6, beingadapted to shift the latch away from the keeper 3.V

For this purpose, cooperating parts are provided on the slide and thecontrolling member 11, the slide having a projection 18 turned upwardlytherefrom and the controlling member having a projection 19, theopposite faces of which are inclined in order that the projection 18 maypass by the projection 19 when moving in both directions. The shiftingand resetting movement takes place when the slide moves from theposition shown in Fig. 3, the slide moving, in this instance, under theaction of a coil spring 20, one end of which is connected to the slideat 21 and the other end of which is connected to the pin 7. The rear endof the slide is turned upwardly and carries a plate 22 in which isthreaded one end of a rod 23 forming the other member of the extensibleplunger, the turning of the rod in the plate 22 varying the length ofthe plunger to accommodate the locking mechanism to receptacles ofdifferent sizes. A wear plate 24 may be secured to the door 17a tocooperate with the end of the rod 23.

The operation of the invention will be understood from the foregoing butit may be summarized as follows: Assume that the door 2 is locked, asshown in Fig. 2, and it is desired to set the locking mechanism topermit the door 2 to be opened once and then locked on closing. The door17a is swung open, permitting the eXtensible plunger to move under theaction of its spring 20, thus causing engagement between the portions 18and 19 which eifects the elevation of the latch 6 and the controllingmember 11, and the yielding of the detainer 10 which immediately returnsto its normal position in advance of the controlling member 11, holdingthe latter in the elevated position with the latch 6 out of cooperationwith the keeper as shown in Fig. 4. Upon the closing of the door 17a,the projections 18 and 19 only engage slightly and this withoutaffecting the position of the latch which has been set on the openingmovement of door 17a. Upon the opening of door 2, the detainer 10 iscarried out of engagement with the controller 11 and the latter with thelatch drops by gravity so that, on the closing of door 2, the nose ofthe latch will ride onto the keeper and interlock therewith, holding thedoor against further opening.
